BUTTON.

SPECIFICATION forming part of Letters Patent No. 390,209, dated October2, 1888.

Application filed May 7, 1888. Serial No. 273,094.

T0 aZZ whom it may concern.-

Be it knownthat I, FRANK B. ORooKs, a citizen of the United States,residing at Los Angeles, in the county of Los Angeles and State ofCalifornia, have invented a new and useful Improvement in Cuff andCollar But tons, of which the following is a specification.

My. invention pertains to buttons having hinged bottoms, and relatesparticularly to improvements in that class of buttons in which thebottom is formed of two bent leaves hinged at the-point of the bend tothe shank of the button. One of the diiiiculties to be overcome in suchbuttons is the liability of the leaves to turn sidewise against theshank when being inserted in the buttonh0lc. Various devices haveheretofore been employed to avoid this difficulty.

My invention consists of the neat and simple means employed by me toavoid this difficulty.

My invention is illustrated in the accompanying drawings, which areconsiderably enlarged for clearness.

Figure 1 is a plan view of the bottom of the button. Fig. 2 is across-section of the button on line a; m, Fig. 1, showing the buttonready to be inserted in the button-hole.

A is the shank of the button. B B are the arm 1 of the bent leaves whichform the bottom of the button. The shank is provided with a stud, C,projecting ouward from the hinge H of the shank in line with the axis ofthe shank. The arms B B of the bentleaves hinged to the (No model.)

shank are provided upon their outer faces with depressions D D,coinciding in lateral position with the stud and equal in depth to halfthe thickness of the stud to receive the stud when the leaves are turnedto be inserted into the button-hole, as shown in Fig. 2, and allow theouter faces of the arms B B to meet.

NVhen it is desired to insert the button in the button-hole, the arms BB are pressed toward each other and the bottoms of the depressions D Dcome into contact with the stud C and prevent the arms from swingingpast the axial line of the shank, but allow the outer faces of the arms&to fit, and are allowed to fit closely together,so that the arms may beeasily inserted in the button-hole.

Now, having described my invention, what I claim as new, and desire tosecure by Letters Patent, is

In a cull button such as set forth, the combination of the shankprovided with the stud C, projecting outward from the hinge of the shankin line with the axis of the shank, and the arms B B of the bent leaveshinged to the shank and provided on their outer faces with depressions DD, coinciding in lateral position with the stud and being equal in depthto half the thickness of the stud.
